:cantlook:Figured out you are good at Flash 🙂 So heres is another task.

Lets say that i want to do falling balls on my Scene.  
These balls all uses the same AS and at somehow i should use a function that i declare myself at frame 1 in my scene. Ive tried, over and over and over again different ways. But i dont know how to use functions.

function = fall(){  
\_y += 1  
if (\_y \> 500)  
{  
\_y = 0  
}  
}

In my world that seems like a fair code for my falling ball.  
On my ball i add  
onClipEvent(enterFrame){  
fall()  
}  
:cantlook:  
But that is not correct. Can somebody please help me out? 🙂 ( My problem is not to get a falling ball, lets say i want to make 2999 falling balls with dublicateMovieClip, etc) :))
